I want to connect two computers using ssh. One is at work, behind a firewall (which I have no access on it), and the other is mine, at home. I want to connect, from home, the one at work at night.
Obviously, the computer at work should be the server, and mine, the client. The point is that the firewall does not allow it, maybe blocking any SYN bit coming from outside of work.
Since I can establish communication when the client is at work and the server is at home, I can make the computer at work try connection periodically, and when I want, take control of the client. Do you know any way of doing that with ssh?
How to setup remote control on Ubuntu 9 for use of windows client ?
Just for use in a home network. I've had a computer for media files for a long time and now I changed from Windows 2000 to Ubuntu 9. I the home network there is some Windows W2k and XP Home and I will use VNC or RDP for remote control of this Ubuntu desktop.
I've no experience of Linux at all and I've seen some notes about this with no luck.
trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface auto lo iface lo inet loopback
[code]....
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?
I have the following problem:I have to networks in remote places.I have an opnvpn client in one network that connects to the the router (openvpn server).My question is,can i connect the network where the openvpn client is,throught the computer with the client to the other network.If yes,how? (please make it an idiot proof anwser because i have limited knowledge about iptables). I was thinking like forwarding (the router in the network with the openvpn client is also firewalling with iptables) the request of the ip class of the openvpn network to the computer with the client,which masquarades the interface
I just added a 2 port network card to a system that is running Fedora 11, but it is INACTIVE. I open the Network Device Control to activate it but there is no network ports in Network Device Control. It is empty.It looks like the system recognize the card and loaded correct driver.
I feel little silly asking this, I accidently removed from my gnome panel my internet connection, volume control and battery indicator on F11. how can I add this back. It does not show up in the add to panel menu and the applications do not give you back the default feel.
I don't know how this happened, but my keyboard copy and paste functions have stopped working. Oddly enough, I discovered that I can only copy and paste by using the third mouse button. Pressing down on the scroll wheel after highlighting text copies the text, pressing it again pastes it Ican still use the Edit-copy and Edit-paste menu functions.
I'm sure it has something to do with all the tinkering I have been doing with my desktop. I have been experimenting with CompizConfig and Cairo dock, changing my themes and things of this nature.
Laptop is Dell Latitude C600/C500 with Pentium III 850Mhz, 256Kb L2 Cache, 256MB RAM, ATI M3 video card, HD 20005 MB and sound card is EES Maestro 3i. After trying to do something with Windows 2000 which was installed on the machine, I decided to put Linux without keeping windows on the machine. First I try with Xubuntu (latest version) which was working but slowly, then I found that Debian could work fine on that machine. I have installed latest version 5.08 and was surprised how goodly old machine can work. I solved problems with screen resolution (change from 800x600 to 1024x768) but I couldn't find solution how to fix problem with sound.
Actually I don't have sound on the machine. I looked for a linux driver for that sound card and Dell is only providing windows drivers. Then I found that I can solve the problem with ALSA drivers but I couldn't find the easy way (or any way at all) to install drivers and to get back the sound. When I click on 'Volume Control' (top right corner of the screen) I get the message: 'Volume control did not find any elements and/or devices to control. This means either that you don't have the right GStreamer plugins installed, or that you don't have a sound card configured.'
Currently I have two separate running laptops on a home network.
The "remote" comp has slackware running on it. I would like to use my main comp to control both, by switching the control of main keyboard(and mouse) between the two comps quickly at will.
I currently have the remote comp running an ssh-server. Is it possible (and practical) to set this up using ssh?......similarly, what c++/c libs are available to build this kind of server?.....
Since a while,the energy-saver shuts down the screeago,it happens after half an hour,but I didn�t set it up in that orders !It makes menervous,short time away from the comp,and soon the screen is dark!And the screensaver will not appear any more,too.I tried to enlarge the times in the energy-manager,created a new profile,switched off the laptopmode-service,nothing helps!And it seems,if there is no possibility to set one of the profiles up,they can only be changed,deleted or newly created.Is there really no place to force it to the required settings?Under the good old KDE3.5,it was no problem,to get it work like I want it to.My 64-bit system runs under openSUSE 11.3 and KDE 4.4.Is here any salvation for my nerves
I have had my thinkpad for just a few short months and, it must be that we are heading into summer, but I am starting to finally run into some overheating issues especially when compiling software for awhile, i.e. kernel.
My question would be, "Is it best to let the built in thermal management take care of the issue, and I just need to know what to tweak, or to put on a script solution such as the tp-fancontrol script?
The computer takes about 5-10 minutes to overheat and the message I get in /var/log/messages is "logger: ACPI group thermal_zone / action THM1 is not defined" then it shuts down.
So, any pointers in the right direction would be appreciated.
I am running slackware-current x86_64 on a Lenovo Thinkpad T500.
My Linux box is eventually gunna sit in my AV setup, so I dont really want a keyboard and mouse hanging off of it once it's setup, so my plan is, the occasions i do need to tinker, to RDP/VNC to it from my Vista laptop.Now I've got the free version of RealVNC running on the Vista laptop and I can bring up the Linux desktop ok, and on first glance it seems ok, but quickly everything proves to not be ok. The mouse and keyboard dont work, say I click on something, nothing happens. However, if I close the VNC session and restart, the previous mouse click has then happened and visible in the VNC session. So it seems things arent updating properly.
Can anybody tell me what is rate control and rate control mode of operation (in data link layer) in an Ethernet interface?. Does it have anything to do with auto negotiation in Ethernet?
I want to implement rate control over network interface. So I have configured Linux PC as a router with netem installed and having two interface cards.
device1----> Linux router with netem ---> device2
device1 connects to eth0 and device2 connects to eth1 of the Linux router. eth0 is configured to connect to the internet and eth1 has a static IP address on a local network. I want to limit bandwidth on devices connected to eth0.So I applied the below rules using tc and tbf.
I am trying to use telnet from linux to connect to the port specified by me and trying to handle control C. But once Ctrl C is pressed the output on the client side stops showing. The server sends data but client doesnt print the same.
We are making an embedded product based on Fedora 10 (this could change, but right now we stick to 10 because it works ok). We have an intel PC board with a build a normal ethernet adapter. Then we have a home build PCI-express card with 4 ethernet adapter build into a Xilinx FPGA (Xilinx Temac) (we got the driver from git.xilinx.com and modified it enough to make it work).
Now, by problem is: How do we control the device names of these ethernet adapters? It would be really nice to have them called eth0, eth1-eth4 in the order mentioned above, such our software always knows which to use for what.
Also: What to we do when the our adapter card is replaced because it is broken? A new card will have new MAC addresses and therefore the adapters will get new names destroying our IP configurations.
I want to control Network manager from the command-line. This worked well enough in Ubuntu 10.04 (with cnetworkmanager, nmcli is another possible choice). Since the upgrade to Ubuntu 10.10 however, a D-Bus exception is raised when I attempt to activate a connection from within a SSH terminal:
org.freedesktop.NetworkManager.PermissionDenied: Not authorized to control networking.
It may have to do with /etc/dbus-1/system.d/NetworkManager.conf; This issue occurs only when I am ssh'd into the machine; in a gnome session I don't get the same issue -- with the same (admin) user account in both cases.
I have a HP Pavilion dv9700 with Ubuntu and Windows Vista (dual boot with Grub).For some reason when I connect to my computer at work (Windows XP machine) in Ubuntu mode, I'm unable to control Outlook 2007. I can activate outlook window, but I cannot browse/open e-mails or folders.When my laptop is in Windows Vista mode everything works fine. This is the only reason for me to still use Windows.
I recently bought a new wireless router to replace my old wireless router. So now I have a spare router. I also have one or two spare NICs around. I read some articles that I can cascade the two routers (connect one LAN port of one router to the WAN port of the other router) so that I can have two subnets such that one subnet is private to the other subnet.I want to create a guest network similar to this configuration such that it can't access other resources. But from what I read, the guest network must be connected to the first router (which is directly connected to the cable modem) and move everything else (i.e, resources that I want to protect) behind the 2nd router.
Well, this isn't what I really want because all the machines behind the 2nd router will be penalized for performance, e.g. NAT will be done twice by each router if any machine needs to access the internet.Since I have a Linux box (running SuSE 11.3), this is what I am thinking and I am not sure if it can be done and I need some advice. I am thinking to install a 2nd NIC on this box, and connect a CAT5 cable from this 2nd NIC to the WAN port of the 2nd wireless router. This little separate network will be my guest network. My goal is to use iptables on the SuSE box to ensure(a) no traffic is allowed from one network to the other network and vice versa. (b) the guest network can share the cable modem to go the internet.I am still picking up the knowledge of iptables so I don't know if this can be done or not
I want to control Network manager from the command-line. This worked well enough in Ubuntu 10.04 (with cnetworkmanager, nmcli is another possible choice). Since the upgrade to Ubuntu 10.10 however, a DBus exception is raised when I attempt to activate a connection from within a SSH terminal:

I'm currently reading through the Linux Advanced Routing and Traffic Control HOWTO from lartc.org, and I'm wondering whether anyone knows of a file where I could keep qos rules persistent across a reboot, similar to /etc/sysconfig/iptables for netfilter. Should I just write my own script, or does something already exist? By the way, iproute-2.6.29-4.fc12.i686.
I have a computer with xubuntu 9.10 and a pc with kubuntu 9.10, and I need to operate on the xubuntu desktop from kubuntu. On KDE there are Krfb/krdc for the desktop, but what can i install on xubuntu to do this?
I have 2 computers with Ubuntu 10.04, when I VNC to the computer I want to control I get the first frame but no subsequent frames. However I can still control the computers mouse and action on anything I want to but I need to be in the same room to see the screen I am VNC'ing to, this sort of defeats the point of VNC as I would like to be able to control the computer from any room in the house.
I need to remotely control my parents' computers to tech support them.My parents use Windows (XP) while I use Linux (Sidux) intuitive application since this is my first attempt at this:

TeamViewer and LogMeIn turn up in my search. Seems like these two are the most popular. How do they stack up to each other?
I have a desktop, a laptop, & a wireless router. The router, unfortunately, doesn't support dd-wrt, tomato, etc firmware, but I would still like to prioritize voip/web browsing over bulk Internet traffic. I hope I can offload the router's missing QoS to my desktop.
Is it possible to have the laptop's connection go from the wall to the router to the desktop, where the desktop could perform the QoS of tomato, then continue on to the laptop? I'm a bit of a noob to networking (subnets?) but do well enough following good instructions.
As for the program that would do the QoS... Don't some Linux machines basically work as super-powered routers for businesses? So there must be some package but couldn't find one. The closest I got was wondershaper but it only shapes traffic for the computer on which it's installed; it might form part of the solution but falls short on its own. other devices should be able to access the Internet normally if the desktop is turned off, & work with other devices like a (jailbroken) iPod Touch.
I work at a cybercafe and i am currently plagued by users who, despite the warning not to, continue to watch porn and use p2p software on my connection. I have done some preliminary research on how to filter the web content as well as to reduce the bandwidth used by p2p software on my network. I found that a solution that has worked for many with regard to web content control is danguardian + squid or privoxy in conjunction with a firewall like firehol or something of the sort. Others use an os like untangle or clear os and install it on a stand alone server. then others use open dns. although i would like the open dns solution, i will need to install a dns client, ddclient and i am a linux newbie so and ddclient requires some compiling or so, and i'm not yet into that. I am also currently not in the mood to dabble into untangle or clear os bcos it will cost me a lot do download the iso's. Internet access is costly over here.
Before i go ahead to implement the steps in any of the tutorials i have seen, i am wondering if such a measure will even help at all.You see, at my cafe, i use my server to share the connection to all my clients. I connect to the internet using a gsm modem. then i have two nic's. nic1 is set to share my connection and my router connects to that nic1. nic2 connects to my router using a static ip to enable communicate with my clients. If i implement something like dansguardian on my server, will it solve the problem for me, that is, do i have to also re-implement the steps i took to configure dansguardian on all the other pc's, that is, my clients?
I like playing around in linux. I have Windows 7 Home Premium which does not have Remote access.I want to be able to control my computer from my android phone. Which verison would be best. I was going to try out Linux Mint 9.
